Book Synopsis Lattice Methods For Quantum Chromodynamics by : Thomas A Degrand
Download or read book Lattice Methods For Quantum Chromodynamics written by Thomas A Degrand and published by World Scientific. This book was released on 2006-09-27 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerical simulation of lattice-regulated QCD has become an important source of information about strong interactions. In the last few years there has been an explosion of techniques for performing ever more accurate studies on the properties of strongly interacting particles. Lattice predictions directly impact many areas of particle and nuclear physics theory and phenomenology.This book provides a thorough introduction to the specialized techniques needed to carry out numerical simulations of QCD: a description of lattice discretizations of fermions and gauge fields, methods for actually doing a simulation, descriptions of common strategies to connect simulation results to predictions of physical quantities, and a discussion of uncertainties in lattice simulations. More importantly, while lattice QCD is a well-defined field in its own right, it has many connections to continuum field theory and elementary particle physics phenomenology, which are carefully elucidated in this book./a /remove
Book Synopsis The Deconfinement Transition of QCD by : Claudia Ratti
Download or read book The Deconfinement Transition of QCD written by Claudia Ratti and published by Springer Nature. This book was released on 2021-06-14 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last few years, numerical simulations of QCD on the lattice have reached a new level of accuracy. A wide range of thermodynamic quantities is now available in the continuum limit and for physical quark masses. This allows a comparison with measurements from heavy ion collisions for the first time. Furthermore, calculations of dynamical quantities are also becoming available. The combined effort from first principles and experiment allows to gain an unprecedented understanding of the properties of quark-gluon plasma. This concise text, geared towards postgraduate students and newcomers to the field, carefully introduces and reviews the state-of-the-art techniques and results from lattice simulations and connects them to the experimental information from RHIC and the LHC.

Book Synopsis Unfolding the Matter of Nuclei by : Società italiana di fisica
Download or read book Unfolding the Matter of Nuclei written by Società italiana di fisica and published by IOS Press. This book was released on 1998 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nucleus and its constituents are a challenging problem. The lectures collected in this book present a broad and comprehensive review of the current knowledge about nuclei.They cover topics such as searching for signatures of the quarks in nuclei with electromagnetic probes and, at much higher energies, for signatures of the quark-gluon plasma in ultrarelativistic nuclear collisions. The attempts to obtain new nuclei in the laboratory are also discussed, as well as the central role played by nuclear physics in the development of weak interactions. Progress in all these areas rests on a deeper theoretical handling of the nuclear and nucleon’s structure. The latter can also be addressed by relying on numerical solutions of QCD on a discrete space-time lattice. The advancement of computational capabilities has spurred a growing interest in this approach. Finally, the book deals with different paths toward solving non-perturbative QCD.

Book Synopsis Understanding Deconfinement In Qcd - Proceedings Of The International Workshop by : David Blaschke
Download or read book Understanding Deconfinement In Qcd - Proceedings Of The International Workshop written by David Blaschke and published by World Scientific. This book was released on 1999-12-29 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume summarizes our contemporary understanding of the deconfinement transition in QCD at finite temperature and chemical potential. Questions as to whether a quark-gluon plasma exists in the interior of dense astrophysical objects or which bound-state signals have to be studied in order to unambiguously detect the QCD phase transition(s) in future heavy-ion collision programmes at RHIC and LHC are addressed. Progress in answering these questions requires a fusion of lattice QCD with other nonperturbative approaches and low-energy effective models for QCD. Experts in these fields present in the book their methods and their results in understanding the deconfinement phenomenon.

Book Synopsis Lattice QCD at the Physical Point by : Thibaut Métivet
Download or read book Lattice QCD at the Physical Point written by Thibaut Métivet and published by . This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The formalism of Quantum Chromodynamics on the lattice (or Lattice QCD) allows to perform ab-initio non-perturbative studies of strong-interaction driven processes, as it provides both a covariant regularisation of the theory of QCD and a natural framework for numerical computations. In this work, after a review of the main features of QCD and a step-by-step presentation of our discretization of QCD on a lattice, we undertake detailed studies of two problems of hadronic physics: the phenomenon of resonant scattering and the structure of the nucleon. The lattice calculations are performed with the Budapest-Marseille-Wuppertal Collaboration's 2+1-flavour gauge configurations, which give access to a wide range of lattice spacings, volumes and quarks masses, thereby allowing to study the sensibility of our results on these parameters, and to perform a complete continuum extrapolation. These configurations include dynamical quarks, and use a clover-improved Wilson QCD action. To investigate the scattering of particles on the lattice, we set up a Lüscher analysis for the emblematic case of pion-pion scattering in the channel of the rho meson resonance. We analyse our data with a variational generalized eigenvalue method, and give an in-depth calculation of the scattering phase-shifts and the corresponding resonance parameters, with a full control of the systematic errors. Our results provide an important step for lattice studies of scattering states, as they are the first to be performed at the physical pion mass, where one can see the actual decay of the rho into two pions. The obtained rho meson parameters are in good agreement with the experimental values, and consistent with a weak pion mass dependence of the coupling between the rho and two pions. As for our probe of the structure of the nucleon, we present a complete extraction of the electroweak isovector form factors, with a comprehensive study of the electric charge squared radius and of the axial charge. Our analysis also feature data at the physical pion mass, which turns out to be crucial in order to perform safe extrapolations to the physical point, as the chiral perturbation theory predicts violent variations of these quantities near the massless-quarks point. Our calculation includes source and sink projections onto the nucleon state, as well as a combined fit method between the two-point and three-point correlation functions to control the contamination of our data by excited states. Although one would need more data to perform a high-accuracy determination of the nucleon radius and axial charge at the physical point with a relevant estimation of the systematic errors, the results we obtain are in good agreement with the experiment and suggest that the excited-state effects are under control. Our analysis also highlights that gauge configurations ensembles near the physical pion mass and with large volumes must be used in order to extract accurate information about the nucleon structure from lattice calculations.

Book Synopsis Predicting Positive Parity Bs Mesons from Lattice QCD. by :
Download or read book Predicting Positive Parity Bs Mesons from Lattice QCD. written by and published by . This book was released on 2015 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: We determine the spectrum of Bs 1P states using lattice QCD. For the Bs1(5830) and B*s2(5840) mesons, the results are in good agreement with the experimental values. Two further mesons are expected in the quantum channels JP = 0 and 1 near the BK and B*K thresholds. A combination of quark-antiquark and B(*) meson-Kaon interpolating fields are used to determine the mass of two QCD bound states below the B(*)K threshold, with the assumption that mixing with Bs(*)[eta] and isospin-violating decays to Bs(*)[pi] are negligible. We predict a JP = 0 bound state Bs0 with mass mBs0 = 5.711(13)(19) GeV. With further assumptions motivated theoretically by the heavy quark limit, a bound state with mBs1 = 5.750(17)(19) GeV is predicted in the JP = 1+ channel. The results from our first principles calculation are compared to previous model-based estimates.
Book Synopsis Measurements of the X c and X b Quarkonium States in pp Collisions with the ATLAS Experiment by : Andrew Chisholm
Download or read book Measurements of the X c and X b Quarkonium States in pp Collisions with the ATLAS Experiment written by Andrew Chisholm and published by Springer. This book was released on 2015-09-14 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis, which won one of the six 2015 ATLAS Thesis Awards, concerns the study of the charmonium and bottomonium bound heavy quark bound states. The first section of the thesis describes the observation of a candidate for the chi_b(3P) bottomonium states. This represented the first observation of a new particle at the LHC and its existence was subsequently confirmed by D0 and LHCb experiments. The second part of the thesis presents measurements of the prompt and non-prompt production of the chi_c1 and chi_c2 charmonium states in proton-proton collisions. These measurements are compared to several theoretical predictions and can be used to inform the development of theoretical models of quarkonium production.
